Diagnostic Imaging

 

Researchers from the Boston University School of Medicine have found evidence of CTE in young athletes’ brains without signs of concussion, indicating the condition is directly tied to head impacts—but not necessarily concussive hits.

By 2030, an estimated 65.7 million people are predicted to be affected by Alzheimer’s disease (AD), a 30 million person jump from today’s total. But, there’s increasing evidence that biomarkers coupled with the correct imaging technique may provide crucial insights into the disease.

Postoperative CT, most notably 3D CT scans, are the preferred imaging technique in evaluating intra-articular screw penetration of proximal humerus fractures, according to a study published in Academic Radiology.

Headaches are common in children, and many tools, often related to neuroimaging, exist to diagnose the situation, but there remains little standardized procedure in approaching individual cases and little clarity around the benefits and risks of pursuing imaging.

A recent retrospective study of brain and spinal MRI of patients suspected or known to have multiple sclerosis showed that the introduction of a structured reporting template produced reports with more adequate information for clinical decision making. The results were published in the American Journal of Roentgenology

Prenatal alcohol exposure changes babies’ faces, suggesting possible neuro effects

Mothers-to-be who drink alcohol, even in modest amounts, are putting their babies at risk of facial changes—and the differences may point to effects in the brain.

Cranial ultrasound a gentle, accurate choice for imaging infants with suspected skull defect

An Italian study published online June 3 in Child’s Nervous System shows that cranial ultrasound is a highly specific and sensitive first-step choice for imaging infants who show signs of craniosynostosis. That’s the birth defect in which the plates of the skull fuse too early, causing abnormal head shape and potentially putting injurious pressure on the brain.

Survey: Rad residency programs must sharpen efforts to draw women, engage med students

New female doctors applying for residency openings in radiology have different reasons for doing so than their male peers, and their priorities may challenge residency-program directors who’ve been trusting the conventional wisdom on things like work-life balance trumping career goals.  

Going by the numbers, radiology is tops in Medicare patient service

No specialty in medicine serves more Medicare beneficiaries than radiology—and this distinction opens all sorts of opportunities to “engage patients and better brand the specialty.”

MRI unlikely to catch speedy CT for initial stroke imaging

Brain MRI may provide more clinical information on some patients with acute stroke, particularly in the detection of acute ischemia and the identification of some stroke-mimicking pathologies. However, every second counts in stroke care—and brain CT has such faster door-to-needle times and better feasibility that it likely will remain the first-line stroke-imaging exam for the foreseeable future.  

FDA finds no harm done by MRI gadolinium retained in the brain

The U.S. Food and Drug Administration’s investigation into MRI contrast agents containing gadolinium, launched almost two years ago, has turned up zero evidence implicating these heavy-metal substances in any harms to the human brain. 

High-end ultrasound with contrast superior for managing abdominal aneurysms

Patients with abdominal aortic aneurysms are better served by contrast-enhanced ultrasound (CEUS) than by color Doppler for follow-up care after receiving endovascular aortic repair (EVAR), according to a study published online May 18 in Clinical Hemorheology and Microcirculation.

POC ultrasound rules out serious ankle injury in children

Point-of-care ultrasound, aka “POCUS,” may not be great for finding what x-rays miss in children’s injured ankles, but it proved specific enough in a recent pilot study to recommend itself for ruling out significant ligament tears and radiographically occult bone damage.

Radiation from head CT in childhood causes no cognitive issues later

Among the misgivings raised by the contemporary spotlight on imaging-related radiation exposure is whether head CT of children might affect their brain health down the road. In a spinoff study at Sweden’s Karolinska Institute, it did no such thing.

In children as in adults, mild brain injury elevates risk of posttraumatic epilepsy

Posttraumatic epilepsy is a known risk for adults who have suffered mild traumatic brain injury (MTBI). The same risk exists for children and teens, according to a longitudinal study published online May 5 in the Journal of Neurosurgery: Pediatrics.
